In order to reproduce this behaviour I created a simple Grails 2.1 HelloWorld app.<\/p>\n
AccountController.groovy<\/p>\n
package helloworld\r\n\r\nclass AmountController {\r\n\r\n def displayAmount(PaymentData paymentData) {\r\n render \"Hello, this is your amount: \" + paymentData.amount.toString()\r\n }\r\n}\r\n\r\nPaymentData.groovy:\r\n\r\n package helloworld\r\n\r\nimport grails.validation.Validateable\r\n\r\n@Validateable\r\nclass PaymentData {\r\n BigDecimal amount\r\n\r\n static constraints = {\r\n amount(nullable: false, min: BigDecimal.ZERO, scale: 2)\r\n }\r\n}<\/pre>\n\u00a0<\/p>\n
Starting this app we can observe rounding of cents in amount to 00 when sending request with dot in amount (http:\/\/localhost:8080\/helloworld\/amount\/displayAmount?amount=12.22<\/a>)<\/p>\n![](\"http:\/\/4.bp.blogspot.com\/-HpL9C9bNj7g\/UHNLQQ4Vc8I\/AAAAAAAAFqI\/U-9tcbLfZ8k\/s320\/Zrzut+ekranu+z+2012-10-08+23%3A18%3A06.png\")
<\/a>
\nWhereas for amount with coma it gives a result with valid cent part (http:\/\/localhost:8080\/helloworld\/amount\/displayAmount?amount=12,22<\/a>)<\/p>\n
